botha re excellent databases. Mysql is better for Reads than Writes.

Postgresql excels when it comes to reliability more than performance.

Wouldn’t a comparision betwee Java and Quercus or Resin be better, as PHP would be using the JVM then

Thanks for this useful code. Is it available on a public repository (e.g. on github?). If not, can I do it?

thanks

Comment on Java Currency Conversion Class by jrtroberts

Here is the fix for the code I found that did not work under Linux.

private void initCacheFile()
{
if (cacheFile == null)
{
if (cacheFileName == null || cacheFileName.equals(“”))
{ /* Old Code that broke under Linux tried to write ExchangeRates.xml to
* /tmpExchangeRates.xml, / is root and app has no permissions to write to root
* filename should be /tmp/ExchangeRates.xml under linux. Note the extra /.
*
* cacheFileName = System.getProperty(“java.io.tmpdir”)
* + “ExchangeRates.xml”;
*/

/*
* New code for fix.
*/
cacheFile = new File(System.getProperty(“java.io.tmpdir”),”ExchangeRates.xml”);

}
}
cacheFileName = cacheFile.getName();
}

I also added some extra methods which I have not posted that allow me to get an array of the Exchange Rate values or a single Exchange Rate.

Thanks for the API, it has worked out for me and my project is almost complete.

Hey,

even if you’re now going with Scala, you probably want to have a look at the play framework.

It has Scala support, but stable versions are mainly for Java so far.

If you prefer easy to use and elegant APIs over bloated stuff like JEE(sorry), have a look.

What Java-friendly alternative would you suggest? I share your criticisms of JSPs, but haven’t found many Java alternatives that are substantially better. I’m no expert, though, I’m hoping I missed something good. Wicket? Tapestry?

Comment on Serve PHP with Tomcat by Carlos Delfino

I have a project that have to link a heavy application in PHP with Java, to run this application it just waits forever the return of the pages in php, I did a test with a simple script and everything is ok, just hangs with very complex scripts . that require calls to several other pages.
What may be happening?
Is there any problem in this format that involves the inclusion of many pages and php classes?
How can I enter debug log in via php code?

Thanks

I am not familiar with easyPHP, but if it contains the fast CGI executable (usually named Php,cgi.exe on Windows) then you should be OK. Regarding MySql: look up the process list to see if you can find the MySql process (mysqld-nt.exe or something similar). If it is not present, it may be necessary to start the server manually or to configure it as a Windows service. Then try to connect to the running server using a client such as mysql.exe command line client. If this works, you can use the various MySql APIs as documented in the PHP manual. For Tomcat, you first need to install the JDBC driver from http://dev.mysql.com/downloads/connector/j/3.1.html and use the JDBC API either directly or use a third-party ORM such as Hibernate.

I’m running a virtual machine with a wamp installed (easyPHP). Is is possible to use the PHP installation that comes with the wamp with tomcat 6, or do I need a completely separate installation of PHP?
I’d also like to know how I can get MySQL to work with PHP+Tomcat.
Thanks in advance.

You can use Scala in Tapestry framework. This will give you benefits of both great lang and FW. cheers
